I run a group that does free software programming education in Seoul. There's a similar group in LA. When I came to Korea, I just set up a meetup account, paid the fee, rented some space, and started teaching people stuff and studying together. Great way to make friends. Been running it for 7 years now. I've had about a dozen or so people come say the group has helped them change their career to IT for the better. A dozen sounds like a small number, but it's a huge impact on those people

So be the change you want to see. If you have a skill that can help people improve their lives, whether it's career or life stuff, share it! Learning a new skill is hard, and having a community to support you in learning, goes a long way
